Fig. 1From: Distribution of surface heat flow and effects on the subsurface temperatures in the northern part of Thrace Basin, NW TurkeyGeological map of the Thrace basin (Siyako and Huvaz 2007) and the distribution of the available temperature/depth data. Basin depths are also shown as contour lines for each kilometer (also from Siyako and Huvaz 2007). The geological cross section (A–B) was taken from Gürgey (2009)Back to article page
